Admittedly, it's The Guardian But

Admittedly, it’s The Guardian But I don’t think the trickiest polling techniques could have elicited strong public support for strikes 20 or even 10 years ago.

“The survey shows that 59% of voters, including 61% of Labour supporters, believe the strikes earlier this month and those scheduled for next month are justified, with opposition from only 29% of voters. ”
“Some 37% of voters say they believe Tony Blair pays too much attention to business while only 14% say he pays too much attention to the trade unions and not enough to business.”

Just as unions abused their power in the 1970s, employers have been abusing theirs for the past decade, and the public mood reflects this.
